TO ALL WHOM I'I MAY CONCERN:

Be it known that I, JAIHUS HASKELL, of Lisbon, in the county of Androscoggin, and State of Maine, have invented certain new and useful improvements in Gultivators; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others to make and use my invention, reference being had.to the accompanying drawings, forming part of this specitication, in which- Figure 1 shows atop plan and'view of my invention.

Figure 2, a side elevation of the same.

Same letters show like parts.

The object of my invention is to provide a cultivator of a particular' construction, with a means of regulating and gauging the depth to which its teeth shall enter the soil, and `to provide a means for accurately gauging the depth' of this entrance inthe manner and by the means hereinafter-more fully set forth and described, -and for other purposes. The frame ofmy improved cultivator is composed of a centre beam, two side pieces, three crcssbraces, and two b'eams which I call splice beams. i i

A shows the centre beam; C the two side pieces; E F G the cross-braces, and H I the splice beams. Upon this frame are placed the arms and handles, bolted and braced as is common. a shows the handles, b the braces, and c the bolting ofthe arms. The frame thus composed is of an A-shape.V Three teeth are tted to this frame, one on the centre beam, at cl,- and one-on each ofthe splice beams, athef. These teeth are secured by passing through the beams of the frame to which they are attached, and then being secured by nuts, the shanks of the teeth being made to pass through the longitudinal and cross-beams of4 the frame at their intersection, where this is possible, and thus form also a bolt to unite the different parts of the implement, for

instance, as at df and e. These 'teeth are made quite long, being sixteen or eighteen inches, or even two feet high, and are composedof three parts, the shank 1, the brace 2, and share 3. The share is made of'a diamondsh-aped sheet or. plate of metal, longer than 'it is wide, and curved downward from the middle to each side; the shape is well illustrated in the drawing. VThis is riveted to the shank l at 4, as seen in the drawing. To the back side ot' the shank 1 is riveted the brace 2, as illustrated. By these means the teeth are secured. Two teeth are placed behind, and one in front of these two, and in front of the space between them. (See tig. 1.) Upon the forwardend of the centre beam A is attached the wheel L, by the adjustable gauge z'. Upon ieach of the splice beams II I are also attached wheels, one on each beam, atj 7c, and bysimilar means. Thus the frame ofthe implement is capable of being borne on its wheels h, j, c. The wheelh passes over that part of the soil y immediately afterward turned up by the tooth M, and the wheelsj and c run in the ful-rows made by the teeth N P. The gauges have pivots, m, upon which they can be turned, and by which they are secured, and slide in clamps or clasps, n, and are by these clamps held atany point desired, so that ythe wheels can be lifted up or lowered as occasion may require. The object of this arrangement ofthe wheels and teeth, to wit, the wheel L in front of the tooth M, and the wheelsj and ic, directly behind the teeth N and P, Ais as follows: rst, to provide a means by which the depth of the entrance of the teeth into the soil can be accurately regulated; second, to enable the implement to have its frame so far raised above the surface of the ground that the liability of the teeth to become loaded and clogged with various substances, such as weeds, clods, die., is wholly or nearly obviated. This object my invention,accomplishes bythe following combination and arrangement, to wit, the combination and arrangement of the three wheels and the three teeth, together with the height or length ofthe teeth, and the position, relative tothe-teeth, of the three wheels bywhich `the depth of the penei tration of the teeth into the soil can be accurately regulated. The position of thc two rear wheelsj is owing to the manner of the attachment of the two splice beams H I, which are chamfered off sc that when united to the inner sides of B and C, they (H and I) are parallel to the centre beam A. In order exactly to regulate the 'depth of penetration of the teeth, itmust be bol-nein mind that the wheel L passes over the. unbroken soil, while thcwheelsj and lc run inthe furrows, therefore j and c must always be dropped as much lower than L as the furrowsare deep. i

The use to which my invention is intended to be devoted is for loosening and cultivating the soil between rows of' growing products, and for further breaking and pulvci'izing the soil after having been' ploughed.

'I do not claim themethod of con'struetingthe frame, nor its form; neither do I claim the construction of the teeth, or the method oi" their attachment; neitherdo I claim a oult-ivator,I the depth eti-whose furrows can be regulated by adjustable wheels or trucks; neithei do I claim the wheels orf the gauges z' or the clamps n;

neither do I claim ,the combination of the wheels with the adjustable gauges z'. B5' the arrangement of the splice bea-ms H I, the two rem` wheels j and 7c are enabled to be' placed in the best position for the accurate gauging of the implement, which could not be sov c'cctunlly attained were they placed, for instance, On the Hering side beams.

But what I do claimJ and desire to secure by Letters Patent, is;

1. The combination cf the three wheels -,j, L", having` their gauges gz', pivots m, and clamps n., with the elongated teeth M N I), when the saune arenrranged in positions relative to euch other on u cultivator frame of the described form, in the manner :ind for the purposes set forth.

2. 4The combination of the splice beams H I with the two rear wheels j and 7c attached and adjustable as set forth, when thc two beams-H I are connected with the beams B C in the manner and for the purposes described.
